Best change plates for a home gym

Change plates are the small plates — usually 0.5 to 10 lb or 0.5 to 5 kg — that let a lifter add weight to a barbell in jumps smaller than a standard 5 or 10 lb plate. Based on maker specs, prices, and published info checked on 2026-09-23, Fringe Sport’s Savage Change Plates offer the best mix of price, tolerance, and warranty in either lb or kg. PRx sells the cheapest single pairs and bundles, while Bells of Steel and XMark cover urethane durability and tight IWF-style tolerance.

What are change plates and who needs them?

Change plates sit outside the collar sleeve on a standard 2 in Olympic barbell and let a lifter progress in smaller increments than a full plate change allows. A lifter stuck at 185 lb on a bench press can add a 2.5 lb pair per side instead of jumping straight to 195 or 205 lb. They matter most on slow-progressing lifts like overhead press, deadlift accessories, or any program that tracks 1–2.5% weekly increases.

Every change plate in this roundup fits a standard 2 in collar opening (or the metric equivalent near 51mm), so they work on most home power racks and standard barbell weight plates setups. Read our how we research page for how facts on this site get checked against maker pages.

Best change plates ranked

The picks above are ranked from our product research. Fringe Sport’s lb and kg Savage lines lead because they combine a stated tolerance, warranty, and full weight range that no other maker in our product research matches on all three counts. Bells of Steel and XMark follow for urethane durability and tight tolerance, and PRx rounds out the list for the lowest entry prices.

How we ranked

Ranking used four factors pulled straight from our product research: published weight tolerance, material and construction claims, price relative to total weight delivered, and any warranty terms listed by the maker. Products with fewer than three researched facts were left out of the picks list entirely, even if they appeared in the maker catalog data.

Where a maker did not list a fact — like XMark’s total set weight or PRx’s warranty terms — that gap is called out in the “skip” notes for that pick rather than guessed at. Any math done to compare products, like cost per pound, is labeled “(our calculation)” and shown separately from maker-stated numbers.

Change plates by weight and material — quick comparison

This table lines up the weight range, material, and stated tolerance for every product with enough sheet detail to compare directly.

Product	Weight range	Material	Tolerance (maker-stated)
Savage Change Plates (lb) — Fringe Sport	1.25–10 lb	Cast iron, rubber coated	+/-1%
Savage Change Plates (kg) — Fringe Sport	0.5–5 kg	Cast iron, rubber coated	+/-1%
Urethane Change Plate Sets — Bells of Steel	1.25–10 lb or 0.5–5 kg	Urethane	Not listed
Urethane Change Plates (pairs) — Bells of Steel	1.25–10 lb or 0.5–1 kg	Urethane	Not listed
Olympic Change Plate Set (kg) — XMark	0.5–5 kg	Rubber over steel core	Under 10 grams
Olympic Change Plate Set (lb) — XMark	0.5–10 lb	Rubber over steel core	Under 10 grams
PRx Cast Iron Change Plates	2.5 lb (size listed)	Cast iron	Not listed
Grind Fitness Change Plates — PRx	2.5–10 lb	Cast iron	Not listed

XMark’s under-10-gram tolerance, tied by the maker to IWF standards, is the tightest figure in our product research. Fringe Sport’s +/-1% is looser in raw terms but still tight enough for most home training — a 2.5 lb plate at +/-1% is off by roughly 0.4 ounces at most.

Cost per pound comparison

Cost per pound varies a lot by material and whether plates are sold as singles, pairs, or full sets. The table below converts sheet prices into a per-pound figure so options are easier to compare; every number here is our own math from the listed prices, not a maker claim.

Product / variant	Price	Total weight	Cost per lb (our calculation)
PRx Grind Fitness 15 lb bundle	$51.99	15 lb	$3.47
Fringe Sport Savage 10 lb pair	$111.00	20 lb	$5.55
PRx Cast Iron 2.5 lb pair (via PRx price)	$26.99	5 lb	$5.40
Fringe Sport Savage 5 lb pair	$65.00	10 lb	$6.50
Bells of Steel Urethane Set (37.5 lb)	$237.99	37.5 lb	$6.35
Bells of Steel Urethane 10 lb pair	$131.99	20 lb	$6.60
Fringe Sport Savage 2.5 lb pair	$41.00	5 lb	$8.20
Bells of Steel Urethane 2.5 lb pair	$48.99	5 lb	$9.80
Fringe Sport Savage 1.25 lb pair	$30.00	2.5 lb	$12.00
Bells of Steel Urethane 1.25 lb pair	$34.99	2.5 lb	$14.00

Bigger plates and bundles almost always cost less per pound than small pairs, since packaging and per-unit handling cost stay roughly flat as the plate gets heavier. PRx’s Grind Fitness bundle is the standout value here — pairing a 5 lb and 2.5 lb set into one $51.99 purchase beats every single-pair option in our product research. XMark’s two full sets are left out of this table because the maker’s page does not list a total set weight, so a per-pound figure can’t be calculated from our product research alone.

kg vs lb change plates — which to buy

Buy the unit your program already tracks. Fringe Sport and XMark both sell matching kg and lb lines from the same catalog, so the choice comes down to whether your main lifts are logged in kilos or pounds, not to any difference in build quality between the two lines.

Mixing units on one bar gets confusing fast — a 1 kg plate (2.2 lb) looks close to a 2 lb plate but isn’t the same weight. If your gym already has standard barbell weight plates in one unit, buy change plates in that same unit to avoid math errors mid-set.

Cast iron vs urethane — what our product research says

Cast iron coated in rubber, like Fringe Sport’s and PRx’s lines, is the cheaper build and covers most of the lowest cost-per-pound options in the table above. Bells of Steel’s urethane line costs more per pound but the maker states urethane is a harder material than rubber, which should mean it resists wear and chipping better over years of use — though our product research does not include independent testing data to confirm that claim.

Neither urethane line from Bells of Steel is IWF-approved, per the maker’s own product pages. If competition prep or federation-approved equipment matters, XMark’s kg and lb sets are the only products in our product research that tie their tolerance claim directly to IWF standards.

Storing change plates at home

Small plates are easy to lose track of in a home gym, especially in sets of six or eight sizes. Bells of Steel sells Change Plate Storage Pegs that bolt onto rack uprights — the Hydra version (5/8 in holes) runs $64.99, and the Manticore version (1 in holes, with UHMW upright protection and rubber stoppers) runs $75.99. PRx also lists a Build Limitless Change Plate Storage unit at $69.99, sized 6 in x 11.5 in x 6.25 in.

Check your rack’s upright hole size against the peg’s listed hole diameter before ordering — a 5/8 in peg won’t fit a 1 in upright hole and vice versa. For broader storage options beyond change plates, see best storage for weight plates.

What to check before buying

Confirm your barbell’s collar sleeve diameter matches the plate’s inner diameter — every product in this roundup lists a 2 in or near-51mm opening, which fits standard Olympic bars but not thinner bars. Also confirm current stock and pricing directly with the maker, since Fringe Sport’s page listed several kg sizes as unavailable at the time our product research was checked, and prices across all these makers change without notice.

If you’re building a full barbell and plate setup rather than just adding change plates, compare 2 inch Olympic weight plates and cast iron weight plates to round out a bar path from warm-up to working sets. For a broader look at the barbell and plates category, see barbells and plates.

Bottom line

Fringe Sport’s Savage Change Plates, in either lb or kg, offer the strongest overall package in our product research: a stated +/-1% tolerance, a 1-year warranty, and prices from $30 to $119 per pair. PRx’s Grind Fitness bundle is the cheapest way to add micro-loading by cost per pound, and Bells of Steel or XMark are worth the extra cost if urethane durability or IWF-style tolerance matters more than price. Confirm current stock and pricing with each maker before buying, since availability and prices change.
